A display includes a thin film transistor, a repair structure for repairing a defect in a signal line coupled to the thin film transistor, the repair structure including a first repair metal layer and a second repair metal layer. The transistor includes a gate electrode, a source electrode, and a drain electrode. A dielectric layer is disposed above the thin film transistor and the repair structure, the dielectric layer defining a repair opening to expose the second repair metal layer, the dielectric layer also defining a contact window that exposes at least one of the source and drain electrodes. A floating electrode is electrically connected to the second repair metal layer through the repair opening, the floating electrode being electrically floated.
